Terminal 37 is the input to be used for safe stop. For instructions on safe stop installation, refer to the section
adjustable frequency drive Design Guide. See also sections Safe Stop and Safe Stop Installation.
In rare cases, very long control cables and analog signals may, depending on installation, result in 50/60 Hz ground loops due to noise from line power
supply cables.
If this occurs, it may be necessary to break the shield or insert a 100 nF capacitor between shield and chassis.
